Coleman or Carson?

I need some help. I went RB heavy in my Keeper League. I have Elliot and Barkley. Who should be my flex play, Telvin Coleman or Chris Carson? Coleman has the better matchup but Carson is the workhorse. What should I do?

I would lean Coleman. He’s been killing it and outside of last week has gotten tons of touches. Think last week the touch count was down due to the blowout.

So both should see plenty of volume but Coleman has an easier matchup
